Bears' Forte has surgery on left knee

Bears running back Matt Forte had arthroscopic surgery on his left knee within the last two weeks, according to multiple sources.

The clean-up procedure followed a postseason MRI. Forte sprained the medial collateral ligament in his knee at Seattle in Week 3, but it is unclear if the surgery stems from that specific injury.

Although Forte ran better toward the end of the season, he averaged just 3.6 yards per carry, down from his 3.9-yard average as a rookie. He finished with 929 rushing yards on 258 carries as the Bears ranked 29th in the league. Forte ran for 1,238 yards on 316 carries as a rookie the year before.

Forte also suffered a partially torn hamstring during offseason workouts before the '09 season.
